Përmbledhja	A longitudinal structured interview applies a fixed, standardised interview schedule to the same participants at two or more points in time. By holding the instrument constant across waves, the method enables genuine within-person change to be measured, trends to be tracked, and causal sequences to be examined with far greater confidence than a single cross-sectional interview can provide. It is widely used in panel studies, cohort research, and programme evaluations.	A cohort study assembles a group of individuals who share a common starting point — typically freedom from the outcome of interest — and follows them over time to observe who develops the outcome. By comparing incidence rates between exposed and unexposed subgroups, researchers can estimate relative risk and absolute risk differences. Cohort studies are the gold-standard observational design for measuring disease incidence and establishing temporal relationships between exposure and outcome.
